This is a right-hand S-cam air brake camshaft with 10 splines on a 1-1/2-inch diameter shaft, and an effective length of 20-3/8 inches (measured to the locking groove).
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It's used in heavy-duty truck and trailer brake systems to convert the rotary motion of the brake chamber pushrod into the linear force that spreads the brake shoes against the drum. Camshafts wear at the splines and head over time, leading to brake adjustment issues; replacement is common when the splines are stripped or the S-cam lobes are worn.
